New THz excitation of planar Goubau line

A. Treizebre, Bertrand Bocquet, Yansheng Xu, Renato G. Bosisio

Quite recently, it has been found that conducting wires lying on a flat dielectric substrate can propagate Terahertz (THz) waves in the same way as conducting wires entirely coated with a dielectric (Goubau line). This phenomenon is interesting because it is a basic requirement to fabricate…

GaNAsSb material for ultrafast microwave photoconductive switching application

Kian Hua Tan, Sonn Fatt Yoon, Charlotte Tripon-Canseliet, Wan Khai Loke, Satrio Wicaksono, Salim Faci, Naïma Saadsaoud, Jean-Francois Lampin, Didier Decoster, Jean Chazelas

We report a photoconductive switch with GaNAsSb as active material for microwave switching application. The GaNAsSb layer was grown by molecular beam epitaxy in conjunction with a rf plasma-assisted nitrogen source and a valved antimony cracker source. The 0.5 μm thick GaNAsSb photoabsorption layer…

Un aperçu des réseaux de capteurs sans fil au Japon : de la gestion de l'énergie à l'architecture des réseaux

Marise Bafleur, Laurent Clavier, Jean-Marie Dilhac

Le Japon abrite une communauté universitaire très active dans le domaine des réseaux de capteurs sans fil. Les applications envisagées à court terme concernent les services à la personne, liées à la santé et à la sécurité notamment. Les téléphones mobiles avec fonction GPS ainsi que les étiquettes…

A method for analyzing the performance of comb-type pilot-aided channel estimation in power line communications

David Buèche, Patrick Corlay, Marc G. Gazalet, François-Xavier Coudoux

In this paper, we propose an original method for analyzing the performance of comb-type pilot-aided channel estimation for power line communications. Our method is based on a unified mathematical decomposition of the channel estimation error, which takes both the signal-to-noise ratio of the pilot…

Monte Carlo Methods for Channel, Phase Noise and Frequency Offset Estimation with Unknown Noise Variances in OFDM Systems

François Septier, Yves Delignon, Atika Rivenq, Christelle Garnier

In this paper, we address the problem of OFDM channel estimation in the presence of phase noise (PHN) and carrier frequency offset (CFO). In OFDM systems, PHN and CFO cause two effects: the common phase error (CPE) and the intercarrier interference (ICI) which severely degrade the accuracy of the…

On the modeling of electric railway lines for the assessment of infrastructure impact in radiated emission tests of rolling stock

Andrea Cozza, Bernard Demoulin

In this paper, we address the problem of testing radiated emissions generated by rolling stock, when carried out on actual railway sites, as prescribed by the standard EN 50121. The idea of assessing infrastructure impact on test results is presented here by means of an electromagnetic model of…
